For a much more thorough introduction, I recommend Types and Programming Languages by Benjamin C. Pierce and Semantic Engineering with PLT Redex by Felleisen, Findler, and Flatt. In a future post I will probably look at some already existing programming languages and examine how much current languages are able to meet my desired features. X ) )( u r ) evaluates to u r ( λx . Many languages like C++ , C# , and Java allow you to create objects that represent simple types like integer or float . Descriptor -> the collection of the attributes of at variable. The effective utilization and control of a computer system is primarily through the software of the system. I seem to have found a good idea where sum types originated and the reason why we don't need them in a programming language. Union types are more orthogonal with respect to product types. I would be willing to place a bet that most computer programmers have, on multiple occasions, expressed an opinion about the desirability of certain kinds of type systems in programming languages. This report describes an extension to the C programming language to introduce the notion of ranged integers, that is, integer types with a defined range of values. Question from Pierce's Types and Programming Languages. There are different types of software that can be used to direct the computer system. Abstract: "Type systems based on intersection types have been studied extensively in recent years, both as tools for the analysis of the pure [lambda]-calculus and, more recently, as the basis for practical programming languages. Good day everyone, This is my first post and I would greatly appreciate your help. On page 56 at the top of the page he has the reduction: ( λx . In an implementation, it is an area of memory that stores the attributes of a variable.
